Summary in the original language of the document
O objetivo do presente trabalho foi investigar a eficiência de extratos de jurubeba (Solanum fastigiatum var. acicularium) no controle do pulgão-da-couve (Brevicoryne brassicae) em experimentos de campo na cultura da couve (Brassicae olereaceae var. acephala). Para a elaboração dos extratos foram utilizadas folhas da planta maceradas e submetidas à técnica de extração a quente por decocção, sendo os extratos pulverizados nos cultivos após o resfriamento. O delineamento experimental foi feito em blocos ao acaso, com 10 repetições, sendo que cada parcela constou de uma linha de cultura com 20 plantas e as avaliações realizadas a cada 10 dias através da contagem do número de pulgões vivos. Os resultados indicaram que houve uma diferença significativa (P < 0,0001) entre o número de pulgões observados nas plantas controle e naquelas que receberam tratamento com os extratos, demonstrando a eficiência dos extratos da planta (S. fastigiatum var. acicularium) no controle do pulgão-da couve.
Summary translation
The objective of this study was to investigate the efficience of jurubeba (Solanum fastigiatum var. acicularium) extracts in the cabbage-aphid (Brevicoryne brassicae) control in field cabbage crops (Brassicae olereaceae var. acephala) experiments. In order to obtain the extracts, the fresh material infusion technique was used, and the extracts were sprayed on the crops after cooling. The random blocks experimental design was utilized, with 10 replicates. Each parcel consisted in a culture line with 20 plants, and the evaluation was conducted every 10 days counting the number of insects alive. The results indicated a significant difference (P < 0,0001) between the number of aphids observed in the control plants and those that received the treatment with extracts, showing the efficience of the plant extracts (S. fastigiatum var. acicularium) in the cabbage-aphid control.
